Tuberculosis (TB) is still one of the leading global infectious diseases. Though most people think about TB testing and the old skin test, the TB blood test has become increasingly popular due to its precision and ease of use. Whether you’re suffering from symptoms or require the test for travel or work, knowing when you require a TB blood test and how much it will cost is necessary, particularly if you’re looking for a blood test near you in urban areas such as Hyderabad.
In this in-depth guide, we shall look at what blood testing for TB entails, when it is needed, its advantages, and costs, especially if you are searching for Hyderabad blood test options or whether to do a Hyderabad blood test at home.
What is a TB Blood Test?
A TB blood test, or an interferon-gamma release assay (IGRA), is a test that detects Mycobacterium tuberculosis, the bacteria that cause tuberculosis. Unlike the skin test (Mantoux), the blood test is done in one visit and delivers quicker, more precise results.
There are two general types of TB blood tests:
- QuantiFERON®-TB Gold (QFT)
- T-SPOT®.TB test
Both tests identify the immune system response to TB bacteria in a blood sample.
When Do You Need a TB Blood Test?
You will need a TB blood test for some reasons. Here are the most typical cases:
- Exposure to Someone with Active TB
If you’ve had close contact with someone who has been diagnosed with active TB, your physician might order a TB blood test even if you are symptom-free. This is particularly the case in schools, workplaces, or healthcare facilities. - TB Symptoms
If you are feeling TB symptoms like an ongoing cough, fever, night sweats, and weight loss, a TB blood test is used to ascertain whether the infection exists within your body. - Pre-Employment or Immigration Screening
Numerous employers, especially in the education and health industries, call for TB testing during pre-employment screening. Likewise, immigration procedures in various nations mandate TB testing reports. - Periodic Screening for High-Risk Persons
Persons with weakened immune systems (e.g., HIV patients, cancer patients, or those on immunosuppressive therapy) tend to be asked to have TB testing periodically. - Travel Requirements
Some nations mandate TB testing as a requirement for extended visas or residence. In these situations, a blood test might be more convenient because it can be completed within a single visit.
Why Get a TB Blood Test Rather Than a Skin Test?
There are several reasons why a TB blood test is preferable to a skin test:
- Single Visit: No follow-up visit required to “read” results like the skin test.
- Increased Accuracy: Fewer false positives due to BCG vaccination.
- Convenient for Home Testing: Done easily through home collection services.
